Fact Checking Process: How We Hold Our Sourcing Intelligence Accountable
At Leeline Group, the accuracy of our sourcing intelligence is the foundation of our clients' business continuity. When your supply chain decisions depend on our guidance, every claim must withstand scrutiny. Our verification process is designed to mitigate the inherent risks of international trade — because a sourcing recommendation you can't verify is a liability you can't afford.
In an industry where supplier directories are often pay-to-play and factory certifications can be forged, we built a different kind of operation. Every page on this site reflects a multi-layered verification system that would catch those fabrications before they ever reach a reader.

Our Process
The Hierarchy of Sourcing Evidence
We do not rely on marketing brochures or unverified supplier testimonials. Every piece of content published by LeelineGroup is built upon a strict hierarchy of sourcing evidence:
Primary Regulatory Data
We verify export/import regulations via GACC (China Customs) and U.S. CBP official bulletins. No third-party interpretations. No outdated PDFs. We go directly to the issuing authority.
3+ government databases checked per guide
Direct Factory Verification
Information regarding manufacturing capacity is derived from on-site audit reports and ISO 9001/14001 certification databases — not supplier self-declarations or marketing collateral.
All supplier claims cross-referenced with ISO registries
Logistics Benchmarking
Freight rate analysis and transit times are cross-referenced with the Freightos Baltic Index and major carrier schedules (Maersk, MSC). We track real-world data, not broker estimates.
Live carrier schedules vs. broker-quoted estimates
Unacceptable Sources
We strictly prohibit the use of generic "Top 10" listicles from affiliate blogs or unverified reviews on B2B marketplaces without secondary verification of the supplier's business license. If we can't independently verify it, we don't publish it.
Authoritative Sources
What We Verify Against
Every sourcing claim is verified against at least one primary-source database in these four categories. We don't cite secondhand summaries or trade blog roundups — we go directly to the issuing body.
Regulatory & Customs
- GACC (China Customs) official tariff bulletins
- U.S. CBP Federal Register notices
- EU TARIC (Integrated Tariff of the European Union)
- WTO Trade Monitoring Database
- MOFCOM (Ministry of Commerce, China) announcements
Certification & Standards
- UL Online Certifications Directory
- ISO 9001 & ISO 14001 registries (ANAB/UKAS)
- FDA Medical Device Establishment Registration
- CE marking Notified Body databases (NANDO)
- FCC OET Equipment Authorization Search
Logistics & Trade Data
- Freightos Baltic Index (FBX) for container rates
- Maersk, MSC, CMA CGM published rate sheets
- Drewry World Container Index
- UN Comtrade Database for trade volumes
- S&P Global Panjiva for shipment records
Supplier Integrity
- NECIPS — National Enterprise Credit Information Publicity System
- SMETA (Sedex) 4-Pillar audit summaries
- amfori BSCI audit platform
- China Judgments Online for litigation records
- World Bank Listing of Ineligible Firms and Individuals
Step by Step
The Review Workflow
Every piece of content passes through five verification gates before it reaches our readers. No exceptions, no shortcuts — whether the article is 500 words or 5,000.
Source Identification
Writers identify and link every factual claim to a primary or verified secondary source. Marketing brochures and pay-to-play directories are rejected at this stage.
Regulatory Cross-Check
A dedicated fact checker searches the relevant regulatory database (GACC, CBP, UL Directory, etc.) and captures dated screenshots as an audit trail.
NECIPS & ESG Screening
Any supplier named in the content is run through NECIPS and ESG audit platforms. Flagged entities are removed or disclosed with a compliance warning.
Editorial Review
A senior editor reviews the fact checker's findings, challenges ambiguous claims, and either signs off or sends the draft back with specific revision notes.
Post-Publication Monitoring
Published content is re-verified on a scheduled cycle. Tariff guides are checked monthly; supplier guides quarterly; evergreen pages semi-annually.
Niche-Specific Verification
The Supplier Integrity Check
Every sourcing guide or recommendation undergoes a Supplier Integrity Protocol. This involves checking the Chinese National Enterprise Credit Information Publicity System (NECIPS) to ensure the entity is not on a "Serious Violations of Law and Dishonesty" list.
We also verify "Golden Supplier" statuses against physical factory locations — cross-referencing registered business addresses with on-site audit GPS data and photographic evidence — to ensure readers are not directed to "shell" trading companies posing as manufacturers.
Our NECIPS workflow is triggered automatically for every supplier mentioned in editorial content. The process queries the system by unified social credit code, checks for administrative penalties, and flags any entity with outstanding enforcement actions or revoked business licenses dating back five years.
For entities that pass the NECIPS screen, we layer on ESG and labor compliance checks using publicly available audit summaries from Sedex Members Ethical Trade Audit (SMETA) and amfori BSCI platforms — cross-referenced with our own on-site photographic evidence.
No supplier appears in a LeelineGroup guide without clearing both the NECIPS check and a secondary address-verification step. If the registered business address and the physical factory GPS coordinates don't match within a 500-meter tolerance, the supplier is flagged for further investigation — not quietly removed from the page.
Ongoing Integrity
Continuous Verification
Verification doesn't end at publish. Tariffs change, certifications expire, and supplier legal statuses shift. Our content is on a scheduled re-verification cadence calibrated to the volatility of the subject matter:
Tariff & Regulatory Guides
Tariff rates, customs classifications, and trade policy content are checked against GACC and CBP sources every 30 days. Any changes trigger an immediate update with a dated correction notice.
Supplier Directories & Rankings
Every listed supplier is re-run through NECIPS. Any entity with a newly recorded violation is flagged, and the article is updated to reflect the current compliance status.
Certification-Dependent Content
Content that references specific certifications (ISO, UL, CE, FDA) is re-checked against certification databases twice a year to catch lapsed or revoked credentials.
Evergreen Guides & Explainers
Foundational content on sourcing strategy and logistics fundamentals is reviewed annually for relevance, accuracy, and alignment with current trade conditions.
Every re-verification event is logged with a timestamp and auditor initials. When an update is required, we publish a dated correction notice at the top of the article — not buried in a changelog.
Accountability in Action
Correction Scenario: When New Evidence Changes the Story
We publish corrections prominently when new information contradicts previously published claims. Here's a real example of our correction protocol in practice:
“An earlier version of our 'Electronics Sourcing Guide' stated that the product met UL standards based on supplier claims. Upon secondary verification of the UL Online Certifications Directory, we found the certification had expired in 2023. The article has been updated to reflect the current non-compliant status of the vendor.”
“Our '2025 China Tariff Guide' originally cited Section 301 rates at 25% for consumer electronics. After the Federal Register published revised rates in November 2024, we updated 14 individual product-line references across the guide within 48 hours — faster than three major competing trade publications serving the same buyer audience.”
When information changes, we change with it — and we tell readers exactly what changed and why. No stealth edits. No quietly archived pages. Just transparent corrections that maintain the trust our audience places in us.

What Our Clients Say About Our Accuracy
“LeelineGroup's fact-checking is what set them apart from the three other sourcing agents we evaluated. They were the only team that showed us independent verification of supplier credentials — not just a list of names from a paid directory.”
Michael Zhang
Founder & CEO, Lumina Home
DTC Brand“We've been burned by bad sourcing data before. LeelineGroup's correction protocol caught a tariff rate change on our behalf and updated their guide before our own logistics team noticed. That's the level of diligence we depend on.”
Sarah Mitchell
VP Supply Chain, NorthStar Imports
Wholesale Buyer“The transparency on their fact-checking page convinced me to try them over a competitor who wouldn't explain their verification process. Two years later, we haven't had a single supplier issue — and I attribute that to their NECIPS-based vetting.”
